TLP3043(S,C,F)

Triac, SCR Output Optoisolators Overview

The TLP3043(S,C,F) is a Triac output optoisolator manufactured by Toshiba Semiconductor and Storage. It features a single channel with 5000Vrms isolation voltage and an over-zero circuit for low EMI switching. The device supports a maximum RMS on-state current of 100 mA and a peak off-state voltage of 400 V. It operates within a temperature range of -40°C to 100°C and is housed in a 6-DIP (7.62mm) package with five leads. Key electrical parameters include a minimum static dV/dt of 200V/µs, a typical holding current of 600µA, and a maximum DC forward current of 50 mA.

Triac, SCR Output Optoisolators Procurement Notes

Verify component authenticity through authorized distributors as the part status is listed as obsolete. Confirm specific suffix requirements (S, C, or F) against datasheet specifications regarding packaging or certification. Cross-reference replacement options such as MOC3043M or VO4154H if supply continuity is required. Ensure compliance with RoHS standards and check for any product change notices affecting availability.

Triac, SCR Output Optoisolators Selection Notes

Select this component for applications requiring high isolation voltage and low noise AC switching. The integrated zero-crossing feature makes it suitable for sensitive electronic environments. Consider the 100mA current limit when sizing for load requirements. Verify that the 400V blocking voltage meets the peak line voltage expectations of the target AC system.

Triac, SCR Output Optoisolators Part Context

This device belongs to the TLP304x series of Triac output optoisolators from Toshiba. It shares architectural similarities with the TLP3041 and TLP3042 but is distinguished by its specific zero-crossing timing and voltage ratings. The series is designed for general-purpose AC power control applications where galvanic isolation is critical.

Triac, SCR Output Optoisolators Replacement Considerations

Publicly confirmed substitute part numbers include MOC3043M from onsemi and VO4154H from Vishay Semiconductor Opto Division. These alternatives are categorized as similar replacements.
